It will darken the more you use it, when it starts being really dark brown/black it usually has stopped etching.<br /><br />Regarding Panel Detail: What's the panel made out of? That will affect what etchant you can use. Elctrolytic etching (using saltwater no less) is a common DIY but you can also use acid.<br /><br />http://www.instructables.com/id/How_to_etch_aluminum_panel_labelsdesigns_with_a_r/<br /><br />You can use a sponge to etch large panels.

I've built some press dies with an image then tried to "enhance" them with ferric, with mixed results. Can reuse the ferric at all or should you use fresh every time.The Farmerhttps://www.blogger.com/profile/09279916536949360121noreply@blogger.com
